Happy Tuesday, everyone! Let’s take a swing through Iowa. I actually have in-laws around Iowa City, so maybe I should forward this on to them, huh?
At 1253PM, CT Iowa City was reporting a temperature of 25 degrees with overcast skies. A line of snow was moving into Iowa City and Cedar Rapids, though it looks to be a quick moving feature at the leading edge of a trough spun off from a much broader system over the Rockies. The larger jet trough at the root of this system is split over the Upper Midwest, allowing for a bit of surface instability and more atmospheric support for a pendant trough than would usually by typical.
The discrete circulation moving into the Great Lakes will also pipe in a bit of stabilizing cold Canadian air through the Upper Midwest. This should buy a fairly tranquil Wednesday morning, however as the broader low moves into the Plains, it will overwhelm the feature that will be moving into the Great Lakes by Wednesday night. Precipitation will build quickly, but a surge of midlevel warmth will lead to a period of freezing precipitation as well on Thursday morning. Cold air will wrap back in for Thursday afternoon, and blustery, snowy conditions will take the rest of the day.

There is a good chance that the middle of the day will be nasty. I think there will be more wintry weather than other outlets, and I am very sure WeatherNation will regret not having hourly forecasts out through Thursday.
